Various objective functions including voltage regulation, reduced transmission line power losses, and minimized reactive power charges for a microgrid are introduced.
Combinations of these goals are attained by solving a multiobjective optimization for the proposed ORPD problem.
This paper presents a comparative study of metaheuristics algorithms in evaluation of economic load dispatch problem in power generating station with MATLAB codes.
In this paper, the formulation of the ELD problems using mathematical illustrations and MATLAB codes were presented.
For economic operation of the power system, the total load demand must be optimally shared among all the generating units with an objective to reduce the total generation cost .
This is also to find out the power outputs of all generating units in power system so that the total cost of generation of the system is minimized, while meeting the load demand, system equality and inequality constraints.This consists of the ELD cost model, Model calculations, cost function and parse solution.It also presents the application of some metaheuristics algorithms (solution algorithms) such as ACSA and PSO in solving ELD problem with MATLAB codes.The ELD problem was modeling using Egbin thermal power station, Nigeria as our case study.Economic Load Dispatch (ELD) is the reduction of the total cost of power generation (which includes fuel consumption and operational cost) of power generating plants while meeting the various loads demand and power losses in the power transmission system.Several considerations are made during energy scheduling, these amongst others are to find out the existing generating units, the distance between load centers and the generating units, identifying the operating limits of each generating units such as the ramp rate limits, maximum and minimum generation level, prohibited zones .Economic load Dispatch is to determine the real and reactive power scheduling in power system this is the minimization of the cost function of different generating units.The essential operation constraints are the power balance constraint, that is, the total generated power must be equivalent to the load demands plus the transmission losses on the power system, and the power limit constraints of the generating units [2-6].The problem of economic operation of a power system is the allocation of the load (MW) among the various units of generating stations in such a way that, the overall cost of generation for the given load demand is minimum.While unit commitment (UC) is an off-line problem, economic dispatch (ED) is an area of online concern.The commitment decisions are made many weeks or months in advance.
